Abstract
Developing thin film-based perovskite solar cells is on the lab scale by considering crucial factors, including degradation, instability, and toxicity, which are undesirable for perovskite photovoltaic technology. In the case of perovskite solar cells, we worked on the controlled processing of nanostructured films for environment-friendly renewable energy sources. In this case, we successfully synthesized nanocrystals by hydrothermal process. The structure and morphology of all hybrid nanoparticles were characterized using a range of techniques such as X-ray diffraction, electron microscope, optical spectroscopic measurements. Several attempts have been made to improve the efficiency of the thin-film solar cell by the change of the fabrication process and optimizing environment-friendly materials addition. Several research works have been carried out under different experimental conditions towards the development of lead (Pb) free, environment-friendly and green perovskite solar cells, along with introducing a new, facile and effective method to develop stable and efficient perovskite solar cell at ambient condition. Fabricated solar cells were tested under different characterization techniques to explore the optical behavior, structural fundamentals, crystallinity, surface morphology, phase formation, defect and disorder, and electrical properties.
